Description
Technical field
The invention belongs to the field of deep of magnesium alloy, and in particular to utilize the life of magnesium alloy cast technique magnesium alloy statue
Production method.
Background technique
Magnesium alloy is a kind of alloy that density is small.It is compared with the technique statue bronze statue of Chinese tradition, same volume
Magnesium alloy weight is 1/4.5th of copper alloy or so.For the price of two kinds of materials, Cu alloy material price is about that magnesium closes
The three times or so of price of gold lattice.The two considers in addition.The main raw material(s) of the technique statue of the magnesium alloy materials of same volume is only
Ten one thirds of bronze have great cost advantage.
In addition, China is the maximum magnesium producing country in the whole world and exported country, actual conditions are that the magnesium factory of various regions relies at present
Cheap resource, the energy and labour manufactures magnesium metal, by primary simple processing, a large amount of waste residues and exhaust gas is left, product
It is sold to overseas.China has turned due to developing century-old left and right of more American-European evening, the external advanced state of the after-product of some high energy consumptions
Backward and developing country is transferred to be produced.Magnesium metal just belongs to this product.Because of value-added content of product and rate of earning foreign exchange thus
It is relatively high.
In addition, the fusing point of magnesium metal only has 651 DEG C, the fusing heat of magnesium is smaller, and the fluidity of molten of magnesium is good, and easy molding is poured
Casting.Since the density of magnesium is small, casting severe is lighter, it is easier to move lifting and transport, this and iron and bronze casting technique
Product have bigger superiority.Due to the above factors, magnesium alloy technique casting is developed, magnesium alloy application range is expanded.
Flourishing national economy, provides more job opportunities for the people, enriches the culture life of the people, make Chinese ancient tradition
Culture is further passed on.
